To all whom 'it may concern.'4

l Be it known that l, Riemann S. Bares, a `citizen of the United States, residing at. Sterling, in the county of Logan and State "of Colorado, have invented new and'useful L Improvements in Plows; ot' which the fol- 'lowing is a specification.

the

meral 1y designates the device proper.

An object o't the invention is to provide 'a "'plow of this character having a plurality of rearwardly extending fingers upon which the sod is adapted to travel as a furrow is made, theidevice being provided with a rotatable drum carrying a plurality 'ot' knives or arms which are adapted to pass between the iiugers of the mold board to return the pulverized condition.

Vith the above and other objects in view which will appear as the description pro- "grcsses the invention resides in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings there has been illustrated a simple and preferred embodiment of theinvention vand in which,

. Figure lis a side elevation of a plow constructed in accordance with the present invention. Fig. 2 is a top plan view ofthe same. Fig. 3 is a detail sectional view of the revolving cylinder, illustrating the manner of attaching the knives or bolts thereto. .Fig. 4 is a detail sectional view illustrating )osition of the spring clutch 37 upon the sharlt as well as the clutch member 34 ycarried by the beveled toothed wheel 29.

In the accompanying drawings the nlnn the present instance the tbody. of the plow lsoil to the furrow niade by the plow in a comprises a pair of spaced channel beams 2.

. These beams extend longitudinally the full 'length of.the body of the plow and have secured betweenthem at their rear end an exthe rear wheel' (i of the device is journaled.

.-.The forward end of the beams 2 have spaced between them a suitable clevis 7 whereby the .1 draft' animals 'are attached. .One of the odset member S supporting a substantiall fu-shaped frame 9 ,within which is mounte en ds of the U-shaped meixibe1 9 are attached to the trame through the medium of an an vbeams 2 is provided with a right angulair- Specicaton ot Letters Patent.

guiar bar l1. Positioned upon the beams 2 through the mediuin'of suitable retaining elements is a journal box 12 and this box is adapted to support a shaft- 13 u on which is integrally mounted a main lan wheel 14 of the' device. The shaft 13is provided with it suitable sprocket wheel 15 mounted u'po`n a suitable collar 16 which is free to ride upon, the shaft 13. This collar 16 is provided' with teeth 17 which are adapted to mesh with similar teeth 18 carried by a collar 19 slidahly mounted upon the box 12. This co1.- lar 1t) is provided with an annular recessed portion which is adapted fo r the' reception of an operating lever 20. The lever 2O is provided with a suitable spring pressed pawl which is yadapted to engage between the teeth of a segment 21 which is secured upon a substantially U-shaped frame 22 connected v`with trame. -It is to be understood that the col., lar 19 is provided with a suitable Spline er1-- gaging a groove within the shaftilB Sothat the said collar is adapted to revolve 'as :the wheel 14 is rotated. Positioned between the outer face of the collar 19 and the inner face of the U-shaped bracket 22 is a helical spring 23, which is adapted to exert pressure be-l tween the head of the frame andthe collar and to normally force the teeth of the collar into engagement with the collar 1G. Y

Mounted in a suitable bearing 24C adjacent the rear of the frame of the device is ein 'axle 25. This axle 25 is j rovded with a suitable gage an endless chain 27 and this chain 27 also cooperates with Va sprocket wheel 15 carf ried by the shaft 17. vTheshaft 25 has its outer. end engaged within a bearing 27 provideduponA a frame 28 carried by the mein ber 2 opposite to that of the sprocket wheel 26. Loosely mounted for rotation upon the outer ond f the shaft 25 adjacent its bearing 27 is a veled wheel'29 and thisbeveled i wheel is adapted to'niesh with a smaller' beveled wheel 30 carried upon a vertical shaft- 31. Thisl shaft 31 has its' upper extremity also mounted in a-su`itabl` bearing carried by theframe 28 andthe. lower p ortion -of'the lshaft 31 is providedwth a' vertically extending cylinder This cylinder 32 is provided 'witha' plltrality of spaced llingers upon suitable .beatings a 'wheel,10.

integrally formed collar 34 which has its outer end provided with suitable teeth 35, which are adapted to be engaged by similar teeth 36 carried by the sliding collar 37. The collar 37 is provided with an elongated slot 38 which is adapted to engage a, suitable pintle 39 carried by the shaft 25 and positioned upon the shaft 25 between the bearing 24 and the outer face of the collar 37 is a helical spring 4.0 which is adapted to exert pressure between the two members and to force the teeth oi the"collar 87 into engagement with the teeth of the collar 34. It will be understood that the cylinder 32 is rotated at a comparatively high rate of speed, and by providing a structure as before described, it will be noted that the beveledcwh'eel 29 meshes with tbe beveled wheel whereby it will kbe freeto rotate until the momentum of the wheel and cylinder rceasea the sliding collar37 beingdetracted against the spring 40 when the beveled wheel 29 ro" I The numeral 41 ber of the device. "This plow'member comprises a share 42 and a plurality of radially disposed rearwardly extending mold arms or members 43. The plow 41 is supported upon a frame of the device .through the medium of suitable rods 44. The outer extremity of one of these brace rods 44 is positioned between the beams 2 and is sustained in operative position through the medium of a suitable bolt 45.

lt is to be understood that thebeams 2 are provided with a plurality of spaced openings so that the plow member/i1 maybe raised or lowered as desired and effectively retained in one of these positions while the share 42 is inoperative. Secured upon the forward end of the plow share 42 is an arm 47. This arm 47'has its upwardlyv extending portion pivotally connected with the offset arm 48 of the lever 49. The lever 49 is provided A.with a spring pressed pawl 50 which is adapted to engage between the teeth fa segment 51 carried by the members 2. By reference toA Fig. 3 of the drawings it will be noted that the cylinder 32 is provided with a plurality of spaced openings and that these openings are adaptedn for engagement with the .reduced threaded extensions 52 carried by the blades 33. The threaded extensions 52 are provided with suitable nuts 53 whereby the said blades 33 are edectively and securely connected with the cylinder 32.

By referentie to Fig. 1' of the drawings it will be noted that the sprocket wheel`30 is permanently secured to the cylinderl and that the said sprocket is provided with a will be noted that when the plow 41 is adates the plow mem-A season justed the cylinder 32 may be also adjusted so as to position 'the knives 33 between the arms or fingers 43 carried by the plow share y42.

From the above description, taken in connection with the accompanying drawings it will be noted that l have provided a comparatively cheap'and thoroughly effective device for the purposes intended, one which is so constructed that when the clutch sleeve or collar 17 is withdrawn from the toothed collar or clutch member 15 the cylinder is free to revolve under its own momentum without interfering with the remainder of the device and it is to be understood that while I have illustrated and described the preferred embodiment of the invention as it now appears to me minor details within the scope of the following; claims may be resorted to without'departin from the spirit or sacrificing any of the a vantages of the device. f

Having thus fully described the linvention what is claimed .as new is:
